Hi Timo, Thanks for you suggestion. I tested step-1 and step-2 again and they ran successfully after I set the number of OpenMP threads to 1. I only plan plan on running MPI codes without any multi-threading. The BLAS implementation I am using is a part of the Intel MKL library which is alre

Can you try setting export OMP_NUM_THREADS=1 before running any of the examples? If you are planning on running MPI-only codes, you don't need to use OpenMP in your BLAS implementation. On Sun, Oct 25, 2020 at 7:25 PM Aaditya Lakshmanan wrote: > > Hi Timo, >I cleaned the previous installa

Hi Timo, I cleaned the previous installation and started with a fresh build. This time after a compilation and installation(with MPI, LAPACK, P4EST and PETSC), trying to run examples/step-1 in the installation directory : cmake . make -j16 ran successfully after which make run resulted i

Hi Timo, I tried another compilation and installation of deal.ii without PETSC, P4EST and LAPACK(by setting the corresponding DEAL_II_WITH_PACKAGENAME=OFF). After successfully completing installation I tried the examples step-1 and step-2 with *cmake . ; make ; make run*, and both of them

Hi Timo, Thank you for your suggestion. I repeated the installation process and this time I didn't run the quick_tests. Rather I changed to examples/step-1 directory in the deal.ii installation and executed the following : *cmake . * *make * which exited with the following error : *Scanni

Running the tests seems to have triggered a rebuild of deal.iII. Can you try running some of the tutorial steps instead? On Fri, Oct 23, 2020, 17:05 Aaditya Lakshmanan wrote: > Hi Wolfgang, >I tried compiling, installing and running the deal.ii tests > interactively on a KNL compute node. Bo

Hi Wolfgang, I tried compiling, installing and running the deal.ii tests interactively on a KNL compute node. Both compilation and installation were seemingly successful but all the tests failed. I have attached the output from make test in the file *test_output.txt*. An example error looks l

Hi Wolfgang, Thanks for your suggestion. I just checked that the Cori login nodes are Haswell processors while the compute nodes on which I wish to run simulations eventually are KNL processors(certain modules are also with that intention). I will use idev to access the compute nodes interact

Aaditya, is NERSC Cori a machine where the front-end node runs a different processor/system than the compute nodes? If so, you're building a library for the compute nodes, and the tests are also built for the compute nodes. But you're trying to run the test executables on the front-end node -

Hi Everyone, I have been trying to install deal.ii on the NERSC Cori System and after a seemingly successful cmake and make install, make test yields failure for all the tests setup. I briefly detail the procedure I followed and the outputs and errors obtained. As a pre-requisite I installed
